The 20th EuCheMS Conference on Organometallic Chemistry was held from 30th June–4th July 2013, and co-sponsored by the RSC’s Catalysis Science & Technology and Dalton Transactions. This was the main international European conference on organometallic chemistry for 2013 and attendees came from all over the UK, Europe and further afield (notably the USA, Japan and various African countries).
Palladium and ruthenium were by far the most represented metals. The presenters were split between those primarily studying fundamentals such as mechanism or characterisation techniques, and those with a focus on practical applications. Several were sponsored or supported by industrial or commercial companies, and others were clearly interested in developing commercialisable products. During the poster sessions, it was clear that some of the students were thinking about industry either in terms of their careers or of commercialising the products that they were working on.
Popular catalytic themes included synthesis of novel compounds and complexes; the improvement of existing routes (including some current industrial processes); and waste reduction. Several presenters mentioned valorisation of waste biomass, a hot topic in the current climate. The cost of catalysts came up a few times. Often, though, the cost of the catalytic metal is secondary to other factors such as the cost of the ligand or of ultrapure solvents or reagents that must be added. It does not always follow that an expensive metal means a more expensive process – in fact the reverse is often the case.
The conference was well attended and the main lecture theatre was full for the final presentation (by Bruno Chaudret, Institut National des Sciences Appliquées, Toulouse, France) at the end of day three. There was standing room only and the mood was exuberant after an inspiring three days.
There was an unscheduled additional presentation for Professor David Cole-Hamilton, of the University of St Andrews, in celebration of his long career in chemistry. The RSC prepared a special issue of Dalton Transactions, co-ordinated by Professors Duncan Bruce and Derek Woollins. Poster prizes were judged by the Young Plenary lecturers and were presented by Professor Dr Eric Meggers. There were nine winners and the prizes were books on organometallic chemistry contributed by Springer and the RSC.
The social activities included a musical interlude following Professor Ei-ichi Negishi’s presentation on Sunday evening. This was followed by a whisky tasting on Monday and to finish off the conference in style on Wednesday evening, a banquet and Scottish ceilidh were held in the glorious Scottish sunshine in the famous Old Course Hotel of St Andrews.
For those who were able to stay, there was an additional morning of chemistry at the RSC Awards Symposium on Thursday 4th July.
The 21st EuCheMS meeting will be held in Bratislava, Slovakia, from 5th–9th July 2015 and is being co-organised by the Czech and Slovak chemistry societies. The website is www.eucomcxxi.eu and will contain more information shortly.

s and even biomass derived feedstocks contain sulfur to some extent which may influence catalytic performance. With more than 100 references, this article may provide a useful source of further information on this very relevant topic.
Meanwhile Elena Corbos and her colleagues at Johnson Matthey Technology Centre, in collaboration with Synchrotron Soleil, France, and University College London, present some original research on the preparation of bimetallic PdAu nanocatalysts. They tested the catalysts for the selective hydrogenation of 2-chloronitrobenzene to 2-chloroaniline and the direct formation of hydrogen peroxide. They found that a Pd-rich surface offered superior selectivity and reaction rates for 2-chloronitrobenzene hydrogenation, while for hydrogen peroxide synthesis, an optimal quantity of gold was required to ensure high productivity.
